Sample Video of the 4500mW IR Cannon going through adjustments manually.. the cannon is just a nickname, it could also be considered an IR Laser as this is basically what you'll find on those cameras.

Arjun, I am wondering the same thing.
I tried "Eprid.com", but the order page and communication link error out.
I am also on the hunt for the same "cannon" illuminator in the 940nm IR range.
VERY COOL! Now you have me thinking.... I wonder if I can take apart an 850nm IR Illuminator and replace them with 940nm.... Looks like I have some research to do!I can't find a source for these online anymore. If you're into do-it-yourself projects, you can use a lens with 850nm IR LED(s) to get a similar effect. I made the one in the photo below a year ago and it has been working well since. I had to come up with my own LED current driver. As I recall it was around 750 mA at 1.6 V.
Arjun, thank you for the lead. I have actually tried to purchase this from CCTV twice.... Both times they took the purchase order, claimed to have sent the product, then after a month or so of haggling, claimed it got lost in the mail, and refund me.Here's another one, but I'm not sure of the seller though

Crazy, right?
AliExpress is like the Wild West. This one's the "regular" price. I'm going to give one a try.JEEPERS!! It appears they've doubled the price since I purchased a pair of them a few weeks ago.
I hadn't noticed that, thanks for pointing that out. Hopefully it'll work fine for my needs anyway.Note that those arent the same. The one you link to shows to be fixed focus 50M/30 degrees 6W light and the one @VorlonFrog linked to is 30-80M/5-80 degrees 4.5W adjustable focus
I recently bought a few of these lights from this seller - unfortunately, the mounting threads aren't cut properly (which means that you can't get more than about 1/4 turn on the mount) but even worse, they don't focus down past about 25 degrees.US $80.64 14% OFF|Video Surveillance 5 80 Degree Adjustable focus 12V Night Vision 850nm IR Infrared Illuminator Light lamp For CCTV Cameras-in CCTV Accessories from Security & Protection on Aliexpress.com | Alibaba Group is the source I used recently. Small, solid, and works exceptionally well. Wish it had better means of on/off control, but hey, you can't have it all...
